Can't assign argument type Function

[chamilaja-yawardana]

I am getting this error "The argument type 'Function' can't be assigned to the parameter type 'void Function()?"

`class BottomButton extends StatelessWidget {
BottomButton({required this.onTap, required this.buttonTitle});

final Function onTap;
final String buttonTitle;

@OverRide
Widget build(BuildContext context) {
return GestureDetector(
onTap: onTap,
child: Container(
padding: EdgeInsets.only(bottom: 10),
child: Center(
child: Text(
buttonTitle,
style: kLargeButtonTextStyle,
),
),
color: kBottomContainerColour,
margin: EdgeInsets.only(top: 10),
width: double.infinity,
height: kBottomContainerHeight,
),
);
}
}`

Try this:

class ReusableCard extends StatelessWidget {
  Color colour;
  Widget? cardChild;
  VoidCallback onPress;

  ReusableCard({required this.colour, this.cardChild, required this.onPress});

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: onPress,
      child: Container(
        margin: EdgeInsets.all(15.0),
        decoration: BoxDecoration(
          color: colour,
          borderRadius: BorderRadius.circular(10.0),
        ),
        child: cardChild,
      ),
    );
  }
}
